SUMMARY OF THE INVENTION

The present disclosure relates to methods and compositions pertaining to coatings, such as paints, for covering a substrate. In various aspects and embodiments the coatings may include a heat reflective metal oxide pigment that, when applied to an external surface of a building helps to reduce the energy consumption in the building. In certain aspects and embodiments the disclosed methods and compositions pertain to heat reflective coatings for metal panels that may be used, for example, for exterior surfaces of buildings. Application of such coating compositions to exterior vertical surfaces (such as walls) of a building provide for lower absorption of solar energy through the coated wall. This, in turn, results in lower wall surface temperatures and lower heat transfer through the coated walls. Thus, the interior temperature of the building is cooler and consequently, less energy is consumed to cool the interior of said building. Vertical walls coated with the present heat reflective wall paints can be effective in lowering cooling energy requirements. In some embodiments, coated exterior surfaces such as provided herein with no or sparse amounts of insulation may exhibit greater reductions in cooling energy requirements that with insulation alone.

Some of the aspects and embodiments described herein are based at least in part on three surprising findings regarding the use of a thick coating (greater than about 5, 10, 12, 15 etc., mils dry film thickness) rather than the prior thin (about 4 mils or less dry film thickness coating). These include: (a) a thick coating having heat reflective metal pigments can be applied to a surface, including a metal panel, EIFS or as a stucco top coat, and still exhibit similar heat reflective properties without a white undercoat (thus obviating a need for a white undercoat or primer); (b) the thick coating can use a relatively lower concentration of heat reflective pigment, thus resulting in coatings that are surprisingly cost effective and commercially feasible; and (c) texturing agents and heat reflective pigments can be included in a single thick coat instead of requiring a two-coat system with a textured bottom coat and a thin heat reflective coating on top.

Certain various aspects and embodiments disclosed herein are based at least in part on findings that the coatings described herein are surprisingly effective when applied to metal panels, such as for example metal panels used architecturally for external walls or roofs as described herein. In this regard, it has been found that coatings having heat reflective pigments applied on metal panels are surprisingly effective in reflecting heat and insulating heat; textured coatings are surprisingly effective in creating desired looks and textures when applied on metal panels; and thick coatings (with and without texturing) are surprisingly effective with regard to the three findings described above.

Some of the aspects and embodiments of compositions and methods described herein are based at least in part on the surprising finding that the heat reflective coatings can reduce interior temperatures and cooling energy amounts and costs when applied to relatively well insulated substrates (such as EIFS) even more than similarly insulated substrates having a non-heat reflective coating. As such certain aspects and embodiments disclosed herein are based at least in part on findings that the coatings described herein are surprisingly effective in further insulating a building when applied to EIFS used in the construction of a building. Moreover, thick coatings (with or without texturing) when applied to EIFS were surprisingly effective with regard to the three findings described above for metal panels. Moreover, the coatings disclosed herein (including textured coatings) have been found to be surprisingly effective in creating desired looks and textures when applied (either by spraying or by trowel) to EIFS.

Certain various aspects and embodiments disclosed herein are based at least in part on findings that the coatings described herein are surprisingly effective when applied as a stucco topcoat. In this regard, it was found that coatings having heat reflective pigments applied as a stucco topcoat are surprisingly effective in reflecting heat and insulating heat; textured coatings are surprisingly effective in creating desired looks and textures when applied as a stucco topcoat; and thick coatings (with and without texturing) when applied as a stucco topcoat are surprisingly effective with regard to the three findings described above. Also, certain of the aspects and embodiments are based on the surprising finding that certain textured coatings such as described herein (with or without heat reflective pigments) can be effectively applied as a stucco topcoat by spraying.

In some aspects and embodiments, coatings as described herein that include heat reflective pigments (with or without texturing agents) have an additional advantage of color fade resistance when applied to a substrate (including when applied as a relatively thick coating such as greater than about 5, 10, 12, 15 etc., mils dry film thickness) such as a metal panel, EIFS or as a stucco topcoat.

Certain aspects and embodiments are based on the surprising finding that when textured coatings are prepared having a certain type (e.g., non-abrasive), size and amount of texturing materials as described herein, the textured coatings can be applied by spraying, including in certain embodiments using an automated sprayer. Moreover, it was also surprisingly found that sprayers could be used to effectively apply a stucco-type coating as described herein, for example a stucco topcoat (such spray application can be performed on site for example in the case of stucco topcoats applied to building walls or in a factory for applications such as metal panels or EIFS materials if desired). Accordingly, provided herein include methods and compositions for applying textured coatings, such as coatings that have a concrete appearance or a stucco appearance, using a sprayer to a metal panel, EIFS or as a stucco topcoat. Such methods and compositions for spray application may include non abrasive texturing materials such as perlite or pumice in the amounts and sizes such as described herein. Also provided are light-weight stucco topcoat coatings (with and without heat reflective pigments) that include perlite and/or pumice texturing materials that may be applied with a trowel or by spraying. It was also found that coatings that include nonabrasive texturing materials such as, for example, perlite and/or pumice (such as when spray applied and/or for example applied as a stucco top coat) are surprisingly advantageous with regard to the pinholes in the final product.

Some aspects and embodiments are based on the surprising finding that non-abrasive texturing materials (such as pumice and/or perlite) having particles of certain sizes can be used to make textured coatings (for example coatings that can be used on metal panels, EIFS, and/or as a stucco top coat) that mimic the hardness and texture of traditional stucco top coats that include abrasive texturing materials. Such non-abrasive textured coatings with such specified particle sizes in certain embodiments have advantages over coatings with abrasive texturing materials, for example for spray application and/or automated spray application and in certain embodiments may have advantages in being more light weight than coatings having abrasive texturing materials. Although such non-abrasive textured coatings with such specified particle sizes can have advantages in spray application, in some embodiments the coatings can also be applied using non-spray methods such as by trowel or brush or the like. In some embodiments a sprayable hard non-abrasive textured coating as disclosed herein includes abrasive texturing materials (such as, for example, silica, silica sand, quartz, calcium carbonate, granite, marble, or limestone) in an amount that is less than 10% by wet weight; or less than 8% by wet weight; or less than 6% by wet weight; or less than 5% by wet weight; or less than 4% by wet weight; or less than 3% by wet weight; or less than 2% by wet weight; or less than 1% by wet weight; or less than 0.5% by wet weight. In some embodiments a sprayable hard non-abrasive textured coating as disclosed herein does not include abrasive texturing materials (such as, for example, silica, silica sand, quartz, calcium carbonate, granite, marble, or limestone). In some embodiments such sprayable hard non-abrasive textured coatings are achieved using pumice as a texturing material, for example pumice having a particle size of at least about 150 microns. Accordingly in certain embodiments provided is a textured coating (with or without heat reflective metal oxide pigments) that includes at least about 7% by wet weight pumice texturing materials having particle sizes of at least about 150 microns; or at least about 175 microns, or at least about 200 microns; or at least about 250 microns; or at least about 300 microns; or at least about 350 microns or at least about 400 microns; or at least about 500 microns; or at least about 600 microns; or at least about 800 microns.

In some embodiments provided is a substrate (such as a metal panel) having a thick coating (greater than about 5, 10, 12, 15 etc., mils dry film thickness) that includes a heat reflective metal oxide pigment at a concentration between about 0.1-6% by weight. In some embodiments provided is a substrate (such as a metal panel) having a thick coating (greater than about 5, 10, 12, 15 etc., mils dry film thickness) that includes a heat reflective metal oxide pigment at a concentration between about 0.1-6% by weight. In some embodiments provided is a substrate (such as a metal panel) having a thick coating (greater than about 5, 10, 12, 15 etc., mils dry film thickness) that includes a heat reflective metal oxide pigment at a concentration between about 0.1-4% by weight. In some embodiments provided is a substrate (such as a metal panel) having a thick coating (greater than about 5, 10, 12, 15 etc., mils dry film thickness) that includes a heat reflective metal oxide pigment at a concentration between about 0.1-3% by weight. In some embodiments provided is a substrate (such as a metal panel) having a thick coating (greater than about 5, 10, 12, 15 etc., mils dry film thickness) that includes heat reflective pigment that is in a concentration that is less than 75%, or less than 60%, or less than 50%, or less than 40% of that required to achieve a reflectivity that is the same or similar to a thin (about 4 mils or less dry film thickness) coating of the same or similar color.

The term “about” as used herein means in quantitative terms plus or minus 10%. For example, “about 3%” would encompass 2.7-3.3% and “about 10%” would encompass 9-11%. Moreover, where “about” is used herein in conjunction with a quantitative term it is understood that in addition to the value plus or minus 10%, the exact value of the quantitative term is also contemplated and described. For example, the term “about 3%” expressly contemplates, describes and includes exactly 3%. Where about is used in conjunction with a range, it is understood that the term applies to both the upper and lower limits of the range.

The phrase “energy consumption” refers to the usage or consumption of conventional forms of energy, e.g. electricity, gas, etc. Thus, the reduction of energy consumption in a building pertains to lower usage of, for example, electricity in said building compared to the same building lacking the coating.

The phrase “coating” as a verb refers to applying, layering, or covering a substrate with a substance such as a paint or finish. As a noun “coating” refers to a substance such as a paint or finish to cover or coat a substrate.

In some aspects and embodiments, provided are textured coatings having a texturing material, for example, methods and compositions are provided pertaining to textured coatings that can be applied robotically or in an automated fashion. In various aspects and embodiments, textured coatings are provided that include a texturing material and a heat reflective metal oxide pigment.

The phrase “textured coating” refers to a coating having a texturing material such as described herein to give the coating a rough, bumpy or otherwise not smooth surface when applied. In contrast, a “smooth coating” as used herein refers to a coating that does not have a texturing material and therefore results in a smooth finish when coated on a surface. In some embodiments, a textured coating of the present disclosure resembles concrete or stucco when coated on a substrate, for example when coated on a metal panel, EIFS or as a stucco topcoat. In some embodiments the coating is sprayed using appropriate pressure to yield a thick, dry film where the profile of aggregate is clearly visible.

The coating as described herein may in some embodiments be applied by spraying (including automated spraying), by a roller, with a trowel, or using any other method for applying coatings.

The term “stucco” refers to a decorative coating for walls as is well known in the art. Stucco is generally made of an aggregate, a binder and water. Stucco may additionally include fibers and/or synthetic acrylics. Stucco as used herein includes coatings referred to as plaster or mortar. In various embodiments stucco may include a mix that includes one or more of sand, Portland cement, lime and water. In some embodiments, stucco may have three coats: (1) a scratch coat (a bottom coat in which a brush or other instrument is used to scratch the surface horizontally or in a crisscross fashion to create a key for the next coat to grip onto, (2) a “brown coat” applied onto the scratch coat that is applied with a smooth finish and (3) a topcoat or finish coat. Three coat stucco is often used for systems in which the stucco is applied to a lath substrate. In some embodiments (for example where stucco is applied directly to masonry or concrete) the stucco has two coats, a basecoat and a topcoat. The stucco topcoat (also referred to as a finish coat) generally provides the desired color and texture of the stucco. The term stucco bottom coat refers to the coating (stucco scratch coat, brown coat or base coat) to which a stucco top coat is applied. Stucco topcoats are traditionally applied using a trowel, however, some of the aspects and embodiments disclosed herein are based at least in part on the surprising discovery that certain coatings as described herein (with and without heat reflective pigments) can be effectively applied as stucco topcoats by spraying achieving a suitable stucco appearance and surface.

In some embodiments of any of the compositions or methods disclosed herein, the heat reflective metal oxide pigment may include pigments having a spinel crystal lattice structure. In some embodiments of any of the compositions or methods disclosed herein, the heat reflective metal oxide pigment may include pigments having a nickel titanate rutile structure.

Heat reflective metal oxide pigments of the present compositions can be prepared by various methods known in the art. Preferably, these pigments are formed using one or more metal alloys that can be incorporated as cations into a corundum-hematite crystal lattice structure, a spinel crystal lattice structure, or a nickel titanate rutile structure For instance, one or more metal alloys is milled to a mean particle size of less than about 10 microns, mixed with other metal oxides, and then the mixture is calcined in the presence of oxygen in a rotary kiln at temperatures ranging from about 800° C. to about 1200° C. to form the pigment. U.S. Pat. No. 6,616,744, the disclosure of which is incorporated herein by reference, describes an exemplary method for forming metal oxide pigments employed in the present compositions and methods.

Heat reflective metal oxide pigments as disclosed herein may include at least one metal oxide pigment capable of reflecting light of infrared wavelengths. Spectroscopic methods for determining reflectance values of a solid substance, including metal oxide pigments, are well known in the art and include, for example, pressing a neat powder of the solid substance and placing the powder sample into a chamber of a spectrophotometer equipped with a reflectance spectroscopy accessory. Such reflectance spectroscopic methods are described, for example, in U.S. Pat. No. 6,454,848.

Coatings

Coating compositions of the present disclosure may be solvent-based, oil-based, or water-based. Solvent-based and oil-based wall paint formulations are well known in the art and include, for example, XL-70 with mineral spirit and toluene; styrene acrylic with aromatic 100 based solvent; vinyl acrylic with mineral spirits and aromatic 100 based solvent; and alkyd coating. Water-based wall paint formulations are well known in the art and include, for example, acrylic resin. In certain embodiments, the present wall paint compositions are water-based formulations comprising a 100% acrylic resin.

Preferably, coatings of the present disclosure include from 35-65% or 35 to 50% solids by weight, from 35-65% or 30 to 40% solids by volume, from 3 to 7% organic solvent, and from 0 to 30% weight percent pigment (pigments include metal oxide pigments, titanium dioxide, and fillers such as formed silica, titanium extenders, and clay). In certain embodiments, wall paint formulations of the invention comprise from 37 to 47% solids by weight, such as from 39 to 45% solids by weight, such as from 41 to 43% solids by weight. In certain embodiments, coating formulations include from 32 to 38% solids by volume, such as from 34 to 36% solids by volume. Preferably, coatings have a density from about 9.1 to about 10.8 pounds per gallon, such as from 9.5 to 10.5 pounds per gallon.

In certain embodiments the coatings of the present compositions and methods are TEX•COTE® SUPER•COTET™, which have varying sheen finishes called Satin Finish Enamel and Platinum Flat Finish, manufactured by Textured Coatings of America (Panama City, Fla.). Other preferred wall paint formulations manufactured by Textured Coatings of America include TEX•COTE® TRIM•COTET™, which have varying sheen finishes called Satin Finish and Semi-Gloss Finish. Both the SUPER•COTET™ and TRIM•COTET™ products from Textured Coatings of America comprise heat reflective metal oxide pigments, and can be used to paint substrates including materials for external vertical walls as well as trimmings on external vertical walls.

The TEX•COTE® SUPER•COTET™ and TRIM•COTET™ is a water-based system formulated with a 100% acrylic resin. Pigments in the TEX•COTE® formulation are selected to provide hide (e.g. coverage), superior weatherability, color retention and low gloss uniformity when exposed to high ultra violet exposure from sunshine. Infrared reflective pigments are added in the TEX•COTE® formulation to reduce heat built-up, to keep the coating cooler, and to save energy. Colors stay vibrant longer due to the infrared reflective pigments used in the SUPER•COTET™ and TRIM•COTET™ formulation. A synthetic flatting aid has been added to the TEX•COTE® formulation to sustain long term “satin finish”. The rheology of the TEX•COTE® system provides flow, leveling and the necessary wet edge during application. The addition of infrared reflective pigments as well as ultraviolet and visible light stabilizers improves the weatherability of the TEX•COTE® coating.

Coating compositions of the present compositions and methods can further include various conventional paint additives, such as dispersing aids, anti-settling aids, wetting aids, thickening agents, extenders, plasticizers, stabilizers, light stabilizers, antifoams, defoamers, catalysts, texture-improving agents and/or antiflocculating agents. Conventional paint additives are well known and are described, for example, in “C-209 Additives for Paints” by George Innes, February 1998, the disclosure of which is incorporated herein by reference. The amounts of such additives are routinely optimized by the ordinary skilled artisan so as to achieve desired properties in the wall paint, such as thickness, texture, handling, and fluidity.

Coatings of the present methods and compositions may comprise various rheology modifiers or rheology additives (such as acrysol), wetting agents, defoamers, dispersants and/or co-dispersants, and microbicides and/or fungicides. To achieve enhanced weatherability, the present wall paints may comprise UV (ultra-violet) absorbers such as tinuvin.

Wall paint compositions of the present invention may further include heat reflective substances other than metal oxide pigments discussed herein. For instance, coating compositions may further comprise ceramic or elastomeric substances, which are heat and/or infrared reflective, so as to provide additional heat reflective benefits.

In some aspects and embodiments of any of the compositions and methods provided herein, a coating of the present disclosure may have heat reflective metal oxide pigments and a texturing material in a single coating composition. This differs from previous applications in which texturing materials were included in a bottom coat such as a primer and the heat reflective metal oxide containing coating was applied as a smooth topcoat. Including both the texturing materials and heat reflective metal oxide pigments in a single coating can, at least in some circumstances have certain advantages such as, for example, obviating the need for a textured primer, the ability to apply both texture and reflectivity in a single coat, and having the textured coating as the top outside coat. In embodiments where the heat reflective metal oxide pigments and textured coatings are included in a single coating, the coating may often be applied relatively thicker (e.g., more than 5 mils dry film thickness, or more than 10 mils dry film thickness, or more than 12 mils dry film thickness, or more than 15 mils dry film thickness) than the heat reflective coatings in situations where the heat reflective metal oxide coat is applied over a textured coating (in such circumstances the heat reflective metal oxide coat has generally been applied at a thickness of less than 5 mils dry film thickness).

Application of Coatings

Coatings of the present disclosure may be applied to a substrate using a variety of well known methods, such as brush, roller, trowel or commercial grade airless sprayer. For instance, platinum SUPER•COTET™ may be applied in some embodiments at 8 mils (1 mil=0.001 inch) wet film thickness, or in certain embodiments for certain textures, the coating is applied at about 6-10 mils wet film thickness. This is approximately equivalent to 2.8 to 3.8 dry mils film thickness. In certain embodiments, coverage rates for SUPER•COTET™ may vary in certain embodiments from about 160 to about 250 square feet per gallon depending on surface porosity and texture. In some embodiments the coatings of the methods and compositions disclosed herein, the coatings are applied between 30-50 square feet per gallon. Representative procedures for applying SUPER•COTET™ are described in the examples below.

Coating compositions presented herein may be applied as many times necessary so as to achieve sufficient coating of external vertical walls. For example, in some embodiments, wall paint may be applied from about 8 mils to about 10 mils wet film thickness, which is equivalent to from about 2.8 to about 3.8 dry mils film thickness.

In certain embodiments, a coating in accordance with the present methods and compositions (including coatings having a heat reflective metal oxide pigment) may be applied at a thickness that is greater than 5 mils dry film thickness; or greater than 8 mils dry film thickness; or greater than 10 mils dry film thickness; or greater than 11 mils dry film thickness; or greater than 12 mils dry film thickness; or greater than 13 mils dry film thickness; or greater than 14 mils dry film thickness; or greater than 15 mils dry film thickness; or greater than 16 mils dry film thickness; or greater than 17 mils dry film thickness; or greater than 18 mils dry film thickness; or greater than 19 mils dry film thickness. In this regard, the present inventors have found that in certain situations, a thicker coating having heat reflective pigments can result in improved heat reflective properties. In some embodiments, the inventors have found that it is possible to use a lower concentration of the heat reflective metal oxide pigment in coatings that are applied relatively thicker (such as greater than 5, or 10, or 12, or 15, mils etc., dry film thickness) can exhibit similar heat reflective properties as thinner coatings having a higher concentration of heat reflective pigments. For example, in some embodiments, a relatively thicker coating (such as greater than 5, or 10, or 12, or 15, mils etc., dry film thickness) has a concentration of heat reflective metal oxide pigment that is less than about 6%; or less than about 5%; or less than about 4%; or less than about 3%; or less than about 2% by weight; or between about 0.1-2%; or about 0.1-3%; or about 0.1-4%; or about 0.1-5%; or about 1-6%; or about 2-6%; or about 3-6%; or about 4-6% by weight. In some embodiments, the present inventors found that under certain circumstances when the coatings are applied at a thicker amount, the coatings exhibit similar heat reflective properties with and without a white primer, thus obviating a need for a white primer.

The coatings of the compositions and methods disclosed herein can in some situations be applied, for example, to external walls of a building on site. Alternatively, in the case of prefabricated materials such as architectural metal panels or EIFS, the coatings may be applied in a factory before shipping to a building site. In certain aspects and embodiment of the present disclosure, a coating such as described herein may be applied to a substrate robotically using an automated sprayer. In certain situations robotic our automated application of coatings may be advantageous in that it can reduce costs by reducing the manpower needed and in some situations can result in a more uniform and consistent coating due to the lack of human error an variation (this may be especially true in the case of textured coatings). Thus certain aspects and embodiments of the present disclosure relate to methods and compositions to reduce or prevent the texturing material interfering with the automated sprayers. As such in some embodiments, coatings (including coatings having heat reflective metal oxide pigments) having non-abrasive texturing materials (such as disclosed herein) that interfere less with automated sprayers are applied in an automated or robotic manner to a substrate such as a metal panel or EIFS. In certain specific embodiments, the non-abrasive texturing material is pumice and or perlite. In some embodiments, coatings (including coatings having heat reflective metal oxide pigments) having texturing materials with smaller particle sizes (for example less than 700 microns; or less than 600 microns; or less than 500 microns; or less than 400 microns; or less than 300 microns; or less than 200 microns) that interfere less with automated sprayers are applied in an automated or robotic manner to a substrate such as a metal panel. In some embodiments, coatings (including coatings having heat reflective metal oxide pigments) having non-abrasive texturing materials (such as disclosed herein and including without limitation perlite and/or pumice) with smaller particle sizes (for example less than 700 microns; or less than 600 microns; or less than 500 microns; or less than 400 microns; or less than 300 microns; or less than 200 microns) that interfere less with automated sprayers are applied in an automated or robotic manner to a substrate such as a metal panel or EIFS. In some embodiments, the texturing material of a textured coating for application in an automated or robotic manner is present in the coating at a concentration of less than 30%; or less than 25%; or less than 20%; or less than 15%; or less than 12%; or less than 10%; or between about 2-40%; or between about 10-30%; or between about 25-35%; or between about 20-30%; or between about 15-25%; or between about 10-20%; or between about 5-15% by weight of the coating.

In some embodiments, coatings (with or without heat reflective pigments) of the present disclosures (such as stucco coatings, coatings that have a stucco appearance on various substrates including metal panels or EIFS, or a stucco topcoat) may be applied in thicknesses disclosed herein using a trowel. In certain embodiments a stucco topcoat coating or a coating having a stucco appearance (with our without heat reflective pigments) such as described herein, is applied using a sprayer. In certain embodiments light weight stucco coatings (including stucco topcoats or coatings having a stucco appearance) as described herein, have surprising properties with regard to the ability to be spray applied and maintain a stucco appearance. In this regard, spray application of stucco coatings (including stucco topcoat coatings and coatings having a stucco appearance) may in certain situations have advantages over traditional trowel applications in that spray applications can reduce labor costs and can result in more consistent finished products. In related embodiments, provided are light weight stucco coatings (including stucco topcoat coatings and coatings having a stucco appearance) that can be applied by trowel or by spraying. In certain embodiments the light weight stucco coatings (including stucco topcoat coatings and coatings having a stucco appearance) include heat reflective metal oxide pigments as described herein. Light weight stucco coatings (including stucco topcoat coatings and coatings having a stucco appearance) can be applied in thicknesses as described herein and can be applied as stucco topcoats or as coatings on substrates such as metal panels or EIFS. In certain specific embodiments, a light weight stucco coating as described herein include a non-abrasive texturing material such as pumice and/or perlite. In some embodiments, the texturing material (such as perlite and/or pumice) of a light weight stucco coating is present in the coating at a concentration of less than 30%; or less than 25%; or less than 20%; or less than 15%; or less than 12%; or less than 10%; or between about 2-40%; or between about 10-30%; or between about 25-35%; or between about 20-30%; or between about 15-25%; or between about 10-20%; or between about 5-15%; by weight of the coating. In some embodiments, light weight stucco coatings (including coatings having heat reflective metal oxide pigments) have texturing materials with smaller particle sizes (for example less than 700 microns; or less than 600 microns; or less than 500 microns; or less than 400 microns; or less than 300 microns; or less than 200 microns). In some embodiments, light weight stucco coatings (including coatings having heat reflective metal oxide pigments) having non-abrasive texturing materials (such as disclosed herein and including without limitation perlite and/or pumice) with smaller particle sizes (for example less than 700 microns; or less than 600 microns; or less than 500 microns; or less than 400 microns; or less than 300 microns; or less than 200 microns) are applied in an automated or robotic manner to a substrate such as a metal panel or EIFS.

Primers

Coating compositions presented herein may be applied to a metal substrate after coating with primers. Exemplary primers include [polyester, epoxy, alkyd, or acrylic primers designed for metal adhesion and corrosion control and are applied in the field or in the factory] TEX•COTE® TEX-BOND™ Primer, a multi-functional low V.O.C. acrylic copolymer pigmented latex system. The TEX-BONDT™ primer contains rheology modifiers to provide non-sag, leveling and film build when freshly applied. This product is ready to use where hard, slick surfaces are difficult to obtain adhesion. The TEX-BONDT™ primer is also for use on PVC, ABS, tiles, painted or unpainted metal approved metal surfaces. Application rate is approximately 200-400 square feet per gallon via brush, spray or roller.

Another exemplary primer which may be optionally applied to a substrate before application of the present wall paint compositions is TEX-COTE™ METAL PRIME Primer, a corrosion resistant water based coating based on a cross-linking acrylic resin binder. This primer is formulated with corrosion resistant pigments and flash rust preventers to provide long-term corrosion protection to metal and adheres to bare steel, galvanize, aluminum, galvalume.

Metal Panels

In some embodiments of the methods and compositions disclosed herein, the substrate to which a coating (such as a textured or smooth coating with or without heat reflective metal oxide pigments) is a metal panel. In certain embodiments the metal panel is an architectural metal panel for external walls or roofing. In some embodiments, the metal panel is for external walls. Metal panels can be insulated or non-insulted single skin metal panels. In some aspects and embodiments of the methods and compositions disclosed herein, the metal panel is made with one or more selected from the group consisting of aluminum, steel, zinc, and copper; in some embodiments the metal panel is galvalume.

In some embodiments, textured coatings as disclosed herein are applied to architectural metal panels (such as metal panels for exterior walls), for example to make the metal panels look like a material other than metal.

Many municipalities restrict the use of smooth metal panels on the visible portion of buildings, but will allow the use of textured metal panels resembling concrete or stucco. As such, in some embodiments, the coating is textured to look like cement or stucco. The use of single skin (non-insulated) panels is growing across the country due to the lower installation cost, but they are currently offered in a smooth finish only; accordingly, the present disclosure specifically provides single skin metal panels (such as for external walls) having a textured coating as described herein.

In some embodiments of the aspects and embodiments disclosed herein a metal panel is coated with a coating having a heat reflective metal oxide pigment. Cooler exterior surface temperatures of metal panels having a heat reflective coating as described herein can allow less heat transfer into the building's interiors, thus reducing energy required for cooling a building having such metal panels on its exterior surfaces (such as walls and/or roofing). In some circumstances, coating a single skin metal panel with a heat reflective coating of the disclosure may obviate the need to use more expensive insulated panels. In the case of insulated panels, one problem that can occur is a loss of adhesion between the metal skin and the urethane foam core due to heat that is emitted through the panel from the exterior surface. Cooler surface temperatures caused by a heat reflective coating as described herein can prevent or reduce such panel-to-foam delamination from occurring.

In certain situations, the textured and/or heat reflective coatings as described herein are applied to metal panels in a factory setting and allowed to cure in the factory before shipping. In such situations it can be advantageous to apply the coatings robotically or in an automated fashion as described herein. Also, in such situations using a quick set resin as described herein also may confer certain advantages as it will allow cured panels to be shipped out of the factory sooner.

Example 1 Preparation of TEX•COTE® REFLECT-TEX™ Heat Reflective Metal Coating

The REFLECT-TEX™ Textured Metal Coating was prepared as a 100% acrylic coating having approximately 50% solids by weight, 46% solids by volume. The REFLECT-TEX™ contains about 1-2% organic solvent, and 34-35% weight percent pigment (pigments include metal oxide pigments, titanium dioxide, and fillers such as formed silica, titanium extenders, clay, and texture aggregates). The density of REFLECT-TEX™ is 10.1 pounds per gallon, and the pigment volume content is about 50 percent on average.

Titanium levels were adjusted depending upon the final desired color to be achieved. The solids content was kept approximately the same in all REFLECT-TEX™ formulations by using inert fillers. Titanium levels varied from none to approximately 5% by weight. Viscosity adjustments were made by adjustment with HEAR viscosity modifiers.

Various colored REFLECT-TEX™ formulations were achieved by combining the above described base coat with approximately 0.1 to 6 percent of metal oxide pigment(s).

For a light, off white color (i.e. Almond), the following formulation, by weight, was mixed together:

Base coat (3.5% titanium) 99.66%  High IR Red Iron Oxide 0.1% Nickel Antimony Titanium Buff Rutile 0.2% Modified Hematite 0.04% 

For a medium (i.e. Tan) color, the following formulation, by weight, was mixed together:

Base coat (3.5% titanium) 98.2%  High IR Red Iron Oxide 0.1% Chrome Antimony Titanium Buff Rutile 0.5% Modified Hematite 0.2%

For a dark gray color (i.e. Gray) the following formulation, by weight, was mixed together:

Base Coat (3.5% titanium) 96.41%  High IR Red Iron Oxide 0.2% Chrome Antimony Titanium Buff Rutile .21% Modified Hematite 3.18% 

Example 2 Effectiveness of Thick Heat Reflective Coatings with and without White Primers

Textured metal coatings for exterior surfaces have been developed utilizing complex mixed metal oxide pigments that reflect solar energy in the near infrared range. This example demonstrates that thick film coatings are have reflective performance equal to thinner film coatings which must be applied over a white primer in order to generate the highest possible total solar reflectance (TSR).

The experimental textured coating was produced and tinted to a light, medium, and dark color using mixed metal oxide dispersions of the corundum hematite, spinal, and rutile structures. The colorimetric CIE data for the three colors is listed in Table 1.

TABLE 1 Color *L *a *b Gray 58.19 0.15 1.08 Tan 58.49 3.47 12.20 Almond 76.39 0.04 12.06

3″×6″ aluminum Q panels were coated with either a titanium dioxide white primer or a carbon black primer. The primers were allowed to cure, and then the textured coating was applied at a wet film thickness between about 12 and 20 mils (dry film thickness between about 6 and 10 mils) over both the black and white primed panels. The coating was allowed to cure 24 hours before testing commenced.

Temperature data comparing the textured coatings over the black or white primer was generated using a modified version of ASTM D4803-97 (Standard Test Method for Predicting Heat Buildup of Exterior Objects). The test apparatus uses a platform designed to hold two adjacent 3″×6″ coated metal panels face up. A 250 watt infrared heat lamp is secured 12″ above the panels and allowed to radiate heat for 20 minutes prior to reading the surface temperature of the coated panels. Temperatures were taken at various sections of the panel using a laser non-contact thermometer. Panels with only black primer and white primer were used as controls. Listed in Table 2 are the surface temperature results.

TABLE 2 Surface Temp/ Surface Temp/ Color Tested Black Primer White Primer Black Primer Control 190° F. N/A White Primer Control N/A 118° F. Gray 153° F. 153° F. Tan 147° F. 147° F. Almond 141° F. 142° F.

Solar reflectance values were generated for the three colors over black and over white. Each of the three colors were compared against a non-IR control at both 6 mils and 30 mils wet (about 3 and 15 mils dry, respectively). Total Solar Reflectance (TSR) values were generated by an outside laboratory using a portable Reflectometer. The results are listed in Table 3.

The data generated from this study demonstrates that the thick textured metal coating containing combinations of inorganic mixed metal oxides reflects the same amount of infrared energy whether it is applied over a black or over a white bottom coat.

This example of a coating resembling the look of stucco contains both pumice ranging in particle sizes from 300-600 microns and Perlite ranging in particle sizes from 150-400 microns along with extender pigments such as calcium carbonate to achieve a semi-course textured, matte finish. This coating is applied at spread rates of 45-70 square feet per gallon or 23-35 mils wet (about 11-18 mils dry). This coating can be applied using either a hopper gun, or texture gun such as Graco 1030, Graco 2030, or Graco 204-000 so that the texture aggregates are evenly distributed across the surface of the substrate. The finished coating has a look resembling stucco. The coating may be applied to a substrate such as a metal panel or EIFS or applied as a stucco topcoat.

Example 6 Automated Application of Textured Coating

The Stucco type coating of Example 5 which contains both Perlite and Pumice sprayed in an automated fashion to a metal panel using a pressure pot system and an automated version of a Graco 204-000 texture gun. The following equipment is used to effectively spray this coating: 1.) ¾″ fluid hose 2.) Pressure pot capable of producing 70 PSI, and Graco 204-000 texture gun supplied with 30 PSI air and ⅛″ “Buck Rogers” style tip.

Example 7 Insulating Properties of Heat Reflective Coatings Applied on IFIS

This example demonstrates that heat reflective coatings as described herein further increase the insulating properties of EIFS as compared to EIFS with non-heat reflective coatings.

A textured coating was produced and tinted to a medium tan color to match the commercial EIFS coating using mixed metal oxide dispersions of the corundum hematite, spinal, and rutile structures. The colorimetric CIE data for the two coatings of same color space displaying a DE=0.25 is listed in Table 4.

TABLE 4 Product *L *a *b Commercial EIFS 58.85 3.24 14.06 Coating TEX-COTE Heat 58.74 3.10 13.88 Reflective EIFS Coating

1 foot square EIFS panels were obtained which were composed of the following components: 1″ polystyrene insulation board, polymer based reinforcing mesh, which is then skim coated with a white acrylic base coat. The commercial EIFS coating was applied by trowel between 28 mils-32 mils wet so that even textured finish was observed. The TEX-COTE heat reflective coating was applied in the same manner achieving wet film thickness of 28-32 mils. Both panels were allowed to cure for 72 hours prior to testing.

Temperature data comparing the textured coatings over EIFS was generated using a modified version of ASTM D4803-97 (Standard Test Method for Predicting Heat Buildup of Exterior Objects). The test apparatus uses a platform designed to hold two adjacent 3″×6″ coated metal panels face up. A chamber exists below each panel which has temperature sensor attached to a digital display, registering the air temperature inside of each chamber. Both chambers are separated by a plastic acrylic divider measuring approximately 1.2 cm in width. A 250 watt infrared heat lamp was secured approximately 12″ above the panels which radiates heat for a period of time prior to reading the surface temperature of the coatings using non-contact laser thermometer. The EIFS coated panels were cut to size and notched so that approximately 2 cm of polystyrene insulation board was recessed into the chamber and an air tight seal was achieved.

Both initial coating surface temperatures and chamber air temperatures were recorded. These two variables were monitored at 15 and 30 minute intervals where temperatures were recorded. This data is listed in Table 5.

Table 5 provides the results of the infrared heat lamp experiments:

TABLE 5 Commercial EIFS Tex-Cote HR EIFS Coating (° F.) Coating (° F.) Chamber Coating Chamber Coating Time Temp Temp Temp Temp Start 70.1 74 70.4 74 30 min 79 196 75.2 155.4 45 min 82.6 196.3 78.3 158.6 1 Hour 88.7 196.9 84.2 156.2 1 Hour 15 min 91.4 196.1 86.9 157.5

As can be seen in Table 45 upon exposure to the heat lamp, the surface temperature of the EIFS coated with infrared heat reflective coating as described herein is substantially lower than EIFS not having heat resistant coatings at each time point. Moreover, the chamber temperature was also lower in the heat reflective coating treated EIFS than non treated EIFS; demonstrating a reduction in the rate of heat flow through the polystyrene insulation board. Thus this data demonstrates that the heat reflective coatings as described herein surprisingly increase the heat insulating properties of EIFS beyond the insulating properties of the EIFS alone.

This stucco coating includes mixed metal oxide pigments which offer both superior fade resistance and reflectivity in the near infrared range. This coating uses a specific pumice aggregate to achieve both a semi-course texture that can either be spray or trowel applied.

When spray applied, the product is atomized using either a Graco 204-000 texture gun, hopper gun, or 2030 texture gun. Application of the finish works best through the 204-000 style gun which utilizes “buck Rogers” tips so that spray pattern can be carefully controlled. Fluid delivery to the gun can be achieved using any number of equipment types such as Graco President 10:1 pump, TexSpray 5900 HD, TexSpray Mark IV, TexSpray mark V, TexSpray 2030, Pressure Pot with hose assembly. Atomizing air to the gun and fluid delivery is adjusted so that a consistent spray pattern is achieved which will allow the product to build onto the surface to achieve 25-40 wet mils. This may be accomplished in either one or two spray passes.
